- INVENTOR. ELMER JOHES- ATTORNEY.S.-

Patented Dec. 28, 1937 UNITED STATES PATENT OFFICE 2,103,948 BEACH UMBRELLA rom'r Elmer Jones, Los Angeles, Calif. Application as 22,1936, Serial No. 91,954 realm. (01. 248-44) This invention relates to improvements in securing devices and has particular reference to a device for securing a beach umbrella into the ground.

The principal object of this invention is to pro- 6 vlde-a. simple mechanism to be secured to the lower extremity of'a beach umbrella, post, or other upright which is to be positioned in the ground.

A further object is to produce a device of this character which is easily attached to the umbrella.

10 A further object is to produce a device which is economical to manufacture, easy to use, and one which will not be easily broken.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawing forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Fig. 1 shows my device in use and connected to 20 the lower extremity of the umbrella staff Fig. 2 is an enlarged detailed side elevation of my device;

Fig. 3 is a cross sectional view taken on the line 33 of Fig. 2 and showing the manner in 25 which my device is clamped to the umbrella stafl and Fig. 4 is a view similar to Fig. 3 showing the umbrella staff as being fixed in the attachment by a' pin extending through the staff and riveted 30 to the attachment.

Ordinarily, beach umbrellas are pointed, and being made of wood, this point rapidly wears away. The result is that the user often finds it difllcult to properly embed the umbrella in the ground- 5 so as to have it stand up against jars or slight wind pressures.

Applicant'has, therefore, devised an element to be secured to the end of the umbrella staff, which element carries a thread so that by rotating the 40 stafi of the umbrella, the point may be caused to screw its way down into the earth, thereby effecting a very solid positioning of the umbrella.

In the accompanying drawing wherein for the purpose of illustration is shown a preferred em- 5 bodiment of my attachment, and in which the numeral 5 designates an ordinary umbrella having a staff 6, my attachment consists of a hollow cone-shaped body. 1, within which is secured the lower end of. the staff, the body having threads 8 extending outwardly therefrom and spirally arranged from the top to the bottom thereof. Adjacent the top, I may employ a band 9 for contracting the upperv portion of the attachment; 5 and in that event I split or slot the top portion on diametrically opposite sides thereof from its up'per end and bend the edges of the slot inwardly to provide penetrating tongues II and I! that bite into the umbrella staff as shown in Figs. 3 and 4 10 and assist in securing the staif within the attachment.

1 may employ a pin ii! for permanently securing the attachment to the staff, and the pin ex-' tends through the staff and body, and is riveted to the latter, as shown in Fig. 4. The slots may be of the bayonet type as shown at I4 in Fig. 2, and

in that event the ends of the pin would be slidably received in the slots for detachably securing the attachment to the staff.

It will be apparent from the above that when my device is attached to the staff of an umbrella and the point brought into engagement with the ground, that by rotating the same, the attachment will bore its way into the surface and effect a very fine support for the umbrella.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes relative to the material, size,

shape'and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claim.

Having thus described my invention, I claim:-

A ground penetrating attachment for an umbrella comprising a hollow cone-shaped body having a. pointed lower end and an open upper end to receive the staff of the umbrella therein, said body being slotted on diametrically opposite sides from the open end and the edges of the slot being in- 40 turned to provide tongues to penetrate the staif, detachable means surrounding the body about the upper end thereof and cooperating with the tongues for securing the staff in the body, and a thread formed on and extending outwardly from the body and spirally arranged about the same from the pointed end thereof.
